Unable to set `performance_insights_enabled` to false

[kris-Nabis]

Found a bug? Maybe our Slack Community can help.

Describe the Bug

Unable to set the variable performance_insights_enabled to false. While set to false Terraform throws the following error:

Error: creating RDS Cluster (dev-db) Instance (dev-db-1): InvalidParameterCombination: To enable Performance Insights, EnablePerformanceInsights must be set to 'true'

Expected Behavior

In our dev environment we may not want to enable performance insights in order to save money. I would have expected to be able to tell the module to set it to false. it would be great if we could make this a bit more dynamic.

Steps to Reproduce

Steps to reproduce the behavior:

1. Create a rds_cluster/aws module
2. set performance_insights_enabled to false
3. Run terraform apply
4. See error

Error: creating RDS Cluster (dev-db) Instance (dev-db-1): InvalidParameterCombination: To enable Performance Insights, EnablePerformanceInsights must be set to 'true'

Screenshots

If applicable, add screenshots or logs to help explain your problem.

Environment (please complete the following information):

Alpine linux
terraform 1.2.5

For anyone coming across this, when any other performance_insights_... options are specified, performance_insights_enabled must be true. In order to set performance_insights_enabled to false, the options must be null or unspecified. E.g.:

  performance_insights_enabled          = local.performance_insights_enabled
  performance_insights_retention_period = local.performance_insights_enabled ? 31 : null
